I have a different setup. But if i plug my ipod into my mb quart with the regular 1.8mm aux plug i get hissing. After i ordered the mb quart ipod interface cable no hissing.

Are you using a 1.8mm plug to rca's. Or the ipod plug(bottom of ipone) to rca's

Is the iPhone plugged into a 12v outlet whole connected to the front 1/8 input plug. I did this playing Pandora from the driver side 12v plug not battery and hot a buzzing noise, ran on battery and it was fine.

I'm just using the standard 1.8 aux plug, male-to-male and the phone isn't connected to a power source.

jmvotto, where is the gain on the EQ? I'm not seeing it for some reason?

Should be 2 little nobs ontop of the EQ... you remove the plastic plugs to access the gain settings. You will need a small screwdriver to adjust them.

If there are input sensitivity at output gain adjustments on top absolutely this is a first step! It hopefully will give more output and allow you to turn amp gains down. Best of all the cost is FREE!

Good call bbuhtx-

What he said.....:)

You may have to unmount the eq from the brackets to get to them.

Another possible test for you Chris (if you're not using one of these already) is to switch from the mini audio output on the ipod to the data output using an adapter.

Mine doesn't like to charge the phone while plugged in but I can live with that with all the other chargers available.

Berg, I don't think it has anything to do with the cable I'm using, because the hissing is still there when the phone isn't plugged in...

Also, I tried adjusting the gains on the EQ all the way down, and the hissing was still there. When I switch the RCA's on the back around (put the tower RCA's on the boat outputs) the hissing gets slightly better, but it's still there. So, I think I've determined it's just bad outputs? A by-product of buying the cheap alternative. Gonna have to live with it I think...

so the hiss, it moves to the inboats when the rca's are swapped around.

Turn the gains UP on the EQ and DOWN at the amp and see what it does. You might still have a freebie solution.
